Although Vanilla Expanded expands upon the Vanilla game, sometimes adding completely new things, I feel like something similar to this would be a interesting spin onto the game.

Although this tweet from Ludeon was a April Fools joke, I genuinely think this could become an actual fleshed out idea.

Even though Rimworld is game about harsh deaths and brutal warfare. I think it'd be a cool idea having Scenarios or Stories of people genuinely having some shops or restaurants, could be similar with the 'Hospitality' mod, just with customers. There could be a scenario starting with very few items, only stuff for starting a restaurant and such.

I doubt this really fits for Vanilla Expanded, but I feel like this is the best area to pitch it full of wonderful modders and people within the community.
